Intensely boring.The film falls into a pattern of following one man's daily routine, and so we get him doing the same things over and over again. Here he is, walking through the woods, talking about trees. Here he is fishing with his boss, the only other character to mention. Here he is not experiencing paranormal events or anything horrifying.
It's well filmed. The cast is okay, although they don't really have anything to work with. The old man gets a couple of moments to act towards the end. There aren't a lot of effects, but those they use are fine. There just isn't anything going on. Boring cyclical activities, and very occasionally something mildly creepy happens.
The horror elements are limited. There's a girl in make-up, there's a big CGI shadow of something we don't get to see, and there's a mild air of fatalism that pervades the entire movie.
I'll avoid spoilers, but I'll tell you that the movie really goes nowhere. The plot doesn't develop, there's no tension, and there's no climax.
